Patented Apr. 22, 1941 CONCRETE STORY PARTITN CONSTRUCTION Jurgen Brandt, Hellerup, Denmark, assigner to Formeta-Eetcn A/ S, Copenhagen, Denmark Application May 10, 1938, .SerialNm 2071343 In Denmark May 12, 1937 claims. (cl. 'i2-c6) been used a mould, which after the casting andl hardening have taken place is removed, whereupon a layer of pallets is applied as a carrier for reeds and plaster.

The object of the present invention is to avoid the employment of such a special arrangement of pallets, and to this end the mould is. constructed in such a manner that vit may be ncluded in the completed construction and serve as pallet for reeds and plaster or for any other coating employed. v

Such a mould may be formed by assembling a number of pallet elements, which may be produced zby the works and supplied in various sizes and shapes, and in the following some preferred shapes will be described with reference to the accompanying drawing, in which Fig. 1 illustrates in top elevation the base of a pallet element,

Fig. 2 the same in side elevation, with moulds applied,

Fig. 3 a vertical section through a portionof a story partition according to the invention provided with a pallet element as that shown in Fig'. 2.

Figs. 4 and 5 two modified manners of construction of a pallet element seen in side elevation and Fig. 6 a sectional View of a portion of a completed story partition.

Referring to Figs. 1-3 the pallet element comprises a number of boards l placed edgewise side by side and spaced slightly apart and interconnected by means of a number of laths 2, the two outermost of which are placed close to the edge of the boards.

As shown in Fig. 2 a mould member 3 oomprising veneer board is arranged between the laths in such a manner that it forms an arch between two laths, and the veneer boards form thus a twin charnier arch, the supports of which are formed by the laths 2. These pallet elements are placed in position prior -to the casting of the story partition illustrated in Fig. 3, and they are carried iby supports not illustrated, whereupon reinforcement rods 4 are arranged between the veneer boards, and these reinforcement-rods are anchored to the walls in any known manner. After this the concrete mass 5 is cast on the pallet elements that are placed closely together all over the area of the ceiling.

In order to provide a secure connection between the concrete and'the pallet elements these may when delivered be provided with anchor bolts 6.

The lower portion of the pallet elements nowform a support for reeds and plaster, which in Fig. 3 is indicated by 1.

Where two pallet elements abut each other there may be loosely disposed veneer arches 8 as indicated to the left in Fig. 3, or the space between two laths may be left open as shown to the right in Fig.y 3, where the concrete is cast directly on to the base l, 2. In this instance it is preferable that the outermost laths are placed right out to the edge of the boards, but by employing pallet elements as illustrated in Figs. 1 and 2 a veneer |board mayV be placed on the boards between the two outermost laths in two neighbouring elements.

The space between the veneer boards 3 and the base l may if desired be filled with an insulation mass, but generally this is not required.

In connection with a pallet element as that illustrated there may be used form boards l, 2 of considerably smaller dimensions than hitherto required, because the pressure of the concrete is transmitted to the supporting points of the pallet elements, when removable supports are placed beneath each lath 2.

As furthermore the pallet elements are included in the building construction there is obtained a saving in costs for pallets which otherwise are used, and at the same time there is produced a considerably more rigid construction with little reinforcement iron and a smaller section of concrete, to the effect that the weight of the total story partition for a given load will be the least possible.

As shown in Fig. 4 there may be employed a triple charnier arch instead of the twin charnier arch shown in Fig. 3, and vthis is cast, and it acts in the same manner, as the twin charnier arches.

Instead of charnier arches there may be employed arches that are rigidly connected to the base, and in this instance there may be employed a corrugated plate 9, Fig. 5, which by means of studs IG is connected to the base l. During the casting of the concrete the mould is carried by means of supports Il that are removed when the concrete has hardened.

The illustrated and described manners of construction of pallet elements are to be considered only examples, as the invention may be varied in several manners without therefore devlating from its scope. Thus there may be produced an assembled pallet element corresponding in size to the area of the ceiling and likewise the pallet element may be assembled on the building ground. The essential object of the invention is that the pallet element is constructed in such a manner that it forms a part ofA the supporting structure and serves as carrier of reeds and plaster or other exterior covering material. It will thus be understood that the invention is not limited to the pallet element but includes likewise for instance a story partition of concrete in which the mould remains within the construction and serves as pallet thereon.

The manner in which such a story partition may be constructed is illustrated in Fig. 6, where like references are used for the same parts as Shown in Fig. 3. Along each lath 2 there are a number of anchor members 6 spaced for instance one yard from each other. Each anchor member is provided with a flat head l2, which is disposed between two insulation discs I3 and. I4 in recesses formed in the boards I and the laths 2. The anchor member 6 is displaceable vertically in a hole I5 in the lath 2, and after the pallet elements are in position in the supports, the laths are covered with an insulation strip I 6.

When the concrete 5 is cast in the mould, the weight of the concrete will to some extent compress the insulation strip I6 and the insulation discs I2 and I3, and when after the hardening of the concrete the supports are removed, the compressed insulation will expand somewhat downwardly thus causing the entire pallet I, 2, 3 to be disconnected from the concrete and be suspended in the anchoring members 6 only. In this manner the only connection between the pallet and the concrete is through the insulation material I2, I3 an-d I6, and there is accordingly obtained an ideal insulation between the stories.

I declare that what I claim is:

l. A concrete story partition, in the construction of which is employed a mould comprising a plurality of pallets placed edgewise in relation to each other, laths4 disposed at intervals across the one side of the pallets and xed to each of them, arch members inserted with their ends between the opposing edges of two neighbouring laths, and a concrete mass cast on the said laths and arches. Y

2. A concrete story partition, comprising a number of pallet members arranged edgewise side by side and slightly spaced apart, laths disposed across the one side of the pallet elements and attached to each of them, mould members inserted each between two neighbouring laths in the form of a twin charnier arch, a concrete mass cast on the mould members and the laths, and means for holding exterior covering material attached to the other side of the pallets.

3. A concrete story partition, comprising a number of pallet members arranged edgewise side by side and slightly spaced apart, laths disposed across the one side of the pallet elements and attached to each of them, mould members inserted each between two neighbouring laths in the form of a triple charnier arch, a concrete mass cast on the mould members and the laths, and means for holding exterior covering material attached to the other side of the pallets.

4. A concrete story partition, comprising a number of pallet elements arranged edgewise side by side, laths attached to and across the pallet elements, mould members each inserted between two neighbouring laths, resilient insulation material disposed on the lath and the adjacent portion of the mould members, and a concrete mass cast on the mould members and the insulation material.

5. A concrete story partition, comprising a number of pallet members arranged edgewise side by side, laths disposed across and attached to each pallet member, mould members each inserted between two consecutive laths, anchor members inserted slidable in holes in the laths, a head formed on each anchor member and disposed within a recess formed in the adjacent pallet member, resilient insulation material `disposed in the said recess between the anchor member head, and the pallet, other resilient insulation material in a recess in the lath between this and the anchor member head, resilient insulation material on the upper side of the lath, and a concrete mass cast on the mould members and the insulation material ln the lath.
